Biological control of internal decay in Scots pine poles: A seven year experiment
1992 - IRG/WP 92-1529
The interactions between key fungi were monitored, by non-destructive and destructive sampling methods, during the course of an experiment on the effectiveness of Scytalidium sp. and Trichoderma spp. for eliminating established infections of Lentinus lepideus (Fr. ex Fr.) Fr. in creosoted Pinus sylvestris poles. Although extensively isolated at the beginning and end of the experiment, Trichoderma ...

The effect of copper/chrome/arsenic (CCA) treated timber on soil fungi
1981 - IRG/WP 1131
The aim of this investigation was to study the effect of CCA treated wood on the microflora of soil with particular reference to copper tolerant soft rot fungi. The IRG collaborative field experiment was designed to monitor the performance of a range of preservative treated hardwoods with particular reference to soft rot in CCA treated timber (Dickinson 1976) and site 33 of this experiment was use...

Termite physical barriers: update on retrofitting Granitgard™ around 'mock-up' buildings after five years
1997 - IRG/WP 97-10226
This field experiment was installed five years ago (March 1992) to evaluate the effectiveness of graded crushed granite stone, commercially marketed under the name Granitgard™, as a physical barrier when retrofitted around 'mock-up' buildings. The field site is located at Walpeup in the semi-arid mallee region of north-west Victoria (360 km from Melbourne), and there are eight ...

Resistance of board materials against fungal decay: A comparative experiment on Kolle flask tests method and direct test method
1985 - IRG/WP 2243
Two sets of plywood (Aucoumea klaineana Pierre) 7 and 11 ply, treated by two preservatives, and untreated, were tested by two methods: 1. Kolle flask test method on malt-agar substrate according to the French standard NF B 51.295; 2. A direct test method in non sterile conditions according to DocNo: IRG/WP/2214. The exposure time far both methods was 12 weeks. After exposure, the degree of attack ...

Whole-of-house protection from subterranean termite attack and damage after four years of field exposure
2008 - IRG/WP 08-10665
This study reports the condition of the whole-of-house termite protection test in tropical Australia after four years. The study was designed to provide maximum protection to whole-of-house timbers in a natural situation posing the highest hazard from subterranean termite populations. The houses were constructed either on concrete slabs or suspended floors using untreated and treated timber fram...

Evaluation of Particulate Materials as a Physical Barrier against Termites under Floor of Experiment House
2017 - IRG/WP 17-10900
In Japan, the damages by the subterranean termites (Coptotermes formosanus and Reticulitermes speratus) are more common. Recently the more attention is paid to the less- or non-chemical methods for termite control. As a non-chemical treatment, physical barriers using particles such as gravels were investigated in terms of environmental safety, cost effectiveness, and duration of performance, and t...

Corrosion verification experiment of the screw driven into CLT
2017 - IRG/WP 17-40816
Japan has abundant forest resources, but we depend on import for 70 percent of the consumed timber. Japan has the vision which promotes the timber self-sufficiency rate 30% to 50% by 2020. Therefore CLT attracts attention as a new timber material. Japan has a climate with high temperature and humidity, and wooden buildings are often treated with chemicals as a measure against biological deteriorat...
